Description of Functions
5.10.2 Internally Time-controlled Blowoff
This function is activated via IO-Link with the "Internally controlled drop-off – time-dependent (I-t)"
value.
The "Blowoff" valve is automatically activated for the time period set as soon as the device leaves "Suc-
tion" mode. This function makes it possible to save an output on the controller. The duration of the
blowoff time is set via the IO-Link "Duration automatic drop off" parameter [0x006A].
The "Blowoff" signal overrides the "Suction" signal, even if the specified blowoff time is very long.
"Blowoff" mode can still be activated in this mode using the "Blowoff" signal input.
5.10.3 Externally Time-controlled Blowoff
This function is activated via IO-Link with the "Externally controlled drop-off – time-dependent (E-t)"
value.
The blowoff pulse is controlled externally via the "Blowoff" input IN
the specified time. A longer input signal does not increase the duration of blowoff.
The duration of the blowoff time is set via the IO-Link "Duration automatic drop off" parameter
[0x006A].
5.10.4 Setting the Blowoff Time
The blowoff time can be entered for internal and external time-controlled blow-off via the IO-Link "Dura-
tion automatic drop off" parameter [0x006A].
5.11 Output and Input Signals
In SIO mode, all input and output signals are connected to the higher-level control unit (e.g. a robot) di-
rectly or via IO fieldbus boxes.
For this purpose, in addition to the power supply, two input signals and two output signals must be con-
nected. The ECBPMi communicates with the control unit via these signals.
5.11.1 Signal Inputs
The ECBPMi only has two signal inputs IN1 and IN2 in IO mode.
The "suction ON/OFF" function is assigned to signal input IN1, while the "blowoff/vent ON/OFF" function
is assigned to signal input IN2.
The signal inputs and thus SIO mode are not available in the "ECBPMi Plus" model.
5.11.2 Signal Outputs
The ECBPMi has two signal outputs.
The function of vacuum limit value H2 (Part Present) is only assigned to signal output OUT2 in SIO mode.
The output is activated when the set vacuum limit value H2 is reached.
The signal output OUT3 can be used, for example, to display the manual control of a robot (e.g.
freedrive).
4 The output is activated when you press the buttons
second.
The output is not used in the "ECBPMi Plus" model.
